Azure web App remote debugging
Unable to connect to the Microsoft Visual Studio Remote Debugger (MSVSMON.EXE)
Issue:
System.Runtime.InteropServices.COMException (0x89710023): Unable to connect to the Microsoft Visual Studio Remote Debugger named XYZ.azurewebsites.net'. The Visual Studio 2015 Remote Debugger (MSVSMON.EXE) does not appear to be running on the remote computer. This may be because a firewall is preventing communication to the remote computer. Please see Help for assistance on configuring remote debugging.at Microsoft.VisualStudio.Debugger.Interop.Internal.IDebuggerInternal120.ConnectToServer(String szServerName, VsDebugRemoteConnectOptions[] pConnectOptions, CONNECT_REASON ConnectReason, Int32 fIncrementUsageCount, IDebugCoreServer3& ppServer)

Solution:
· This exception is related to MSVSMON.EXE
· This exe should be running to perform remote debugging.
· We can verify this exe in kudu site-> Process Explorer
· Once we enable remote debugging setting,
· Please verify whether this EXE is running or not before performing remote debugging.
· If you see this exe and still not able to remote debug then
o kill that exe.
o Disable remote debugging setting
o Enable remote debugging setting
o Verify that exe is running.
o Restart web app if needed.
· The exception message is also indicating about firewall setting.
· To enable remote debugging for Visual Studio the port number 4020 should be open.
I hope this helps.
